POWER SUPPLY: Demand Management At Work
Recent Western Cape Business News
Since 2008 the Western Cape has saved 231 megawatts of which 200 megawatts were saved by implementing CFL’s and geyser control systems in the region.
During the past year, the focus was on customer education and behaviour, Eskom says.
Various workshops with industry partners with the likes of Fedhasa, City of Cape Town and SAPOA took place.
With these partners, Energy Efficiency Forums were established for commercial and office buildings and two successful workshops took place during September and October last year.
“Eskom is currently addressing the sustainability of CFL’s in Khayelitsha where in the past two months, it has replaced 140 000 of the 2006 CFL’s with new lamps to ensure sustained savings.
Meanwhile the Cape Chamber of Commerce says it would like to see fruition of the plans to introduce differential tariffs to encourage commerce and industry to save electricity during peak hours and to do work which consumed large amounts of current at night when surplus capacity was available.
During peak hours when demand is high Eskom has to start up its diesel-powered gas turbines to produce the extra electricity required. These gas turbines have very high operating costs and this is one of the reasons why the price of electricity has increased so sharply.
If the load could be shifted, the Chamber says, the electricity infrastructure would be used more efficiently and discounted power prices during the night would be an important incentive for industry to reschedule production and save money. Eskom already applied differential tariffs for some direct customers such as the mines, but the system could be extended through the distributors to other industrial and commercial customers.
